Description
Katarzyna Łacinnik and co-authors (2025) recover pure nickel metal from the black mass of shredded lithium-ion batteries. Recycling these batteries matters as spent cells pile up as hazardous waste. The team took nickel-rich sulfate solutions from leaching the black mass. They plated the nickel out on a stainless steel cathode, using coated titanium anodes, at sixty degrees. Two ways of running the bath were compared.
Letting the nickel level fall during the run gave uneven deposits that flaked, though efficiency was decent. Feeding the bath with dissolving nickel hydroxide kept the level steady. Added helpers in that bath lifted efficiency to between 78 and 93 percent. The deposits came out bright, even, and up to half a millimeter thick, at over ninety percent purity. The authors conclude that steady concentration and the right additives make electrowinning a practical way to close the nickel loop in battery recycling.
